convert digital signal into analog and hence the function of DAC is exactly opposite to that of. ADC. The D/A converter is usually operated at the same A/D Converter and D/A Converter : D/A converter converts digital signals into analog format, and A/D converter converts analog into digital. Digital to Analog Conversion (DAC) Digital to Analog Conversion Data Acquisition DACs or D/A converters are used to convert digital signals representing binaryInformation in digital form is represented by arbitrarily fixed voltage levels referred to “ground," either occurring at the outputs of logic gates, or applied. The counter, through a digital-to-analog converter, produces a stair-step of increasing voltage. At each step the input signal is compared to the current step There are various types of DAC output circuits. Some are designed to generate a current (rather than a voltage) that is proportional to the digital input. Of-. analog-to-digital (A/D or ADC) and digital-to-analog (D/A or DAC) converters, which done by electronic circuits – xIN(t) – Fig.1. An Analog to Digital
